Putting review aggregation in product's navigation

Do you guys think it's a bad idea to put a review aggregation page in a product's navigation? Such as: "Which Brand of Men's Shampoo Is Best for You?"​

Rand suggests against it in this Whiteboard Friday as it interferes with a product's funnel, but I wonder if including it in navigation will give a domain and that page increased authority for a head keyword, such as "men's shampoo."

I would be hugely surprised if you got anything from doing this at all, but the only way to tell what it will do for you, is to test it. I highly doubt you would get any sort of a penalty for doing this, but I certainly wouldn't roll it out across the site.
